The Greening of Detroit is celebrating 30 years of planting 100,000 trees and community building in Detroit on December 3, with a Grow Tomorrow’s Detroit initiative with a donation of $25 or more.

Each year, The Greening of Detroit nonprofit recruits between 500 and 3,000 volunteers to help plant trees, clean up gardens and parks around the city, and work at the tree nursery. There are plenty of opportunities to dig in the dirt and make a positive difference in Detroit.
